Signal processing

ABSTRACT: Multiplications and Accumulations find tremendous applications in the domain of Digital Signal Processing (DSP). On contrast to this, currently there is an immense requirement of hardware dedicated to serve the purpose of speed enhancement. Reversible circuits are being deployed on a large scale to design the Multiply Accumulate units with the advent of quantum computing. In this paper, we present a real time development model of a 4 x 4 Multiply Accumulate unit by exploiting reversible logic for optimizing energy consumption. KEYWORDS: Multiplications and Accumulations, DSP, Reversible Logic, Reversible Gates, Power Dissipation, Reversible Multiplier. I. INTRODUCTION One of the most crucial issues of concern in current technology…

However, the learning-based algorithms are generally resource intensive and require a long time context, which makes them hard to implement in real time processing. In [16], Nakatani et al. proposed harmonicity-based dereverberation (HERB) methods, which modeled RIR inverse filters as a ratio of the direct path component to the received signal. The design of the inverse filters exploited the harmonicity characteristics of the speech signal and estimated the filter coefficients in two distinct…

detection of pollutants in soil, water, air with biological sensors which has attracted interest as these facts are directly related to human health. Plus these sensors averted the need of setting up a lab and gathering samples for investigation which is expensive, time consuming and invasive. High sensitivity, minimum weight and large bandwidth makes fiber optic sensors the optimum photonic devise in radiative environment like nuclear power plants, where there is a need of evaluation and…

2 OFDM SYSTEM:- OFDM system is divided into three parts 1. multi carrier modulation 2. frequency division multiplexing 3. Orthogonal frequency division multiplexing. 1.Frequency division multiplexing:- Frequency Division Multiplexing is a form of signal multiplexing which involves assigning non – overlapping frequency ranges or channels to different signals or to each user of a medium. A gap is left between each of these channels to ensure that the signal of one channel does not overlap with…

Each totaltraffic graph in the method section shows the server or the client with the above RTT and Window Size as incoming and outgoing traffic. The horizontal axis represents the time in seconds and the vertical axis represents the measured traffic in bytes. The graphs presents the increase of traffic once the experiments starts and ends. Case 3. In comparing the window size and RTT staying the same, the traffic decrease once the window size increase. In comparing RTT and the window size…

results of dynamic behavior (Cunha, A., Caetano, E., Calc¸ada, R., and Delgado, R., 1999, ‘‘Modal identifi- cation and correlation with finite element parameters of Vasco da Gama Bridge,’’ Proceedings of IMAC 17, pp. 705–711, Kissimmee, FL, Feb). The more advanced methods overcoming drawbacks of the PP method when the modes are spaced closely are frequency domain decomposition method (FDD) (Brincker R, Zhang L, Andersen P (2001) Modal identification of output-only systems using frequency domain…

The general model introduced in Fig.4.10 is commonly used to design stable high-order modulators. If a chain of integrators is used to form the loop filter, two main modulators typologies exist [1, 5, 8]: a cascade of M delaying integrators is used to form the filter, where the feedback and the input signals are being fed to each integrator input with different weight factors a_i and b_i (Fig.4.11). The transfer function of the signal filter, L_0, is: while the feedback filter L_1 can be…

This artifact is primary based on sample rates and to see the effects of sample rates by using Sinusoidal waves. Sinusoidal waves can be represented using frequency and period. The Frequency of a Sinusoidal wave is the number of complete cycles that happen in a particular period of time or in a given sample. The Period in terms of Sinusoidal waves, is the time it takes to perform one complete cycle. The Sinusoidal wave is a series of identical cycles happening repeatedly. The sample rate is the…

The experimenters followed their experimentation with analysis of the data obtained. The experimenters first contemplated the applicability of the Probe Comp test signal to biological systems. The experimenters reasoned that the test signal was not an effective description of a biological system because the test signal did not exhibit the noise present in biological systems. While considering the observations of the oscilloscope and biological systems, the experimenters considered which settings…

Chapter eight of the text Sound and Recording by Francis Rumsey and Tim McCormick, discusses the principles of digital audio, and contrasts digital with analog. The text also illustrates how digital and analog work together to produce desired sound. In the world of audio there are two types; digital and analog. Analog can be described as physical or tangible in a sense, being etched onto some type of media. Digital however, is a representation of the audio waveform, which is converted into a…
